New Spiro‐Sesquiterpenoids from the Marine Sponge Myrmekioderma sp

Three new spiro‐sesquiterpenoids, myrmekiones A−C (1–3), were isolated from the marine sponge Myrmekioderma sp. collected from the South China Sea. The structures of 1–3 were experimentally illuminated though comprehensive NMR spectra, X‐ray diffraction analysis and calculated ECD. These three compo...

Summary:Three new spiro‐sesquiterpenoids, myrmekiones A−C (1–3), were isolated from the marine sponge Myrmekioderma sp. collected from the South China Sea. The structures of 1–3 were experimentally illuminated though comprehensive NMR spectra, X‐ray diffraction analysis and calculated ECD. These three compounds possessed a special spiro skeleton. Compound 1 was characterized by a chamigrane‐type structure, it is the first time to obtain the single‐crystal of this type of oil compounds. 2 and 3 were a pair of diastereoisomers that possessed an acorane skeleton. This study expands the chemical diversity of marine origin spiro‐metabolites.
